JOHN THOMAS WILLIAMS, or Los ANGELES, CALIFORNIA.

' STILE-HOBNING MACHINE.

Application med Janu ry-aims. Serial No. 610,509.

To all whom it may concern Be it w a citizen of the United States, and a resident of'Los Angeles, in the county of Los Angeles and State-of California, have invented a new and Improved Stile-Homing Machine, of which thefollowing is a full, clear, and exact description.

This invention relates to woodworking machinery,'and more particularly to such class of machinery which includes a rotary I cutter toward which the work may .be ad vanced for shaping.

As the invention is preferably carried out,

the same provides a stile horning machine, that 1s, a machme for horning or giving a reverselycurvedshaping to an end of a winand rapidly to be given a plurality of chaI'' acteristically dissimilar movements to bring thestile end to be horned into the .field of operation of the cutter in such manner as to cause the, single cutter to horn the stile end to shape the same to a surface presenting a portion concavely curved and convexly curved. i

' Another object of the invention is to provide work holding and guiding means of thekind last indicated and having associated therewith sequentially operable carriage shifting means, whereby one of such-means may conveniently be pedal-operated and the other mayconveniently be hand-operated, to facilitate convenience, minimize fatigue of the attendant, and make rapid production possible and highly economical.

A further object is to provide in amachine as described, a mounting for the Car riage such that the same is limited to a movement of translation, preferably in a straight line, toward and away from the cutter, and to a movement of rotation to advance the work toward and away from the cutter; and, in connection with such carknown'that I, JoHNT. VILLIVAMS,

atthe end of one of such movements of the carriage, the carriage is then and then only ad ustedrfOr its other movement.

Still a further object isto provide a struci tureofrthe kind above specifiedin which a,

single spring means or equivalent may be employed for normally holding thecarriage away'from the cutter, and yet a means autol o a matically functionmg, assoon as a movement of translation of thecarriage toward the cutter is completed, to urge the carriage toward its movement of rotation. A further object of the invention is t provide, in a machine of the above nature,

the pedal and handle aforesaid so arranged that the handle need be employed, after completion of the second characteristic movement of the carriage, only to move the car riageback'to the position it occupied at the completion of its first characteristic movement.

Still another-object of the invention is to provide a guard for the cutter, but adjustriage mounting, to design the same that able relative thereto, and automatically adjusted as the result of the various carriage movements for maximum protective action at all times during the completestile horning operation.

Other objects and aims of the invention,

more or less broad than those stated above, I

together with the advantages inherent, will be in part obvious, and in part specifically referred to in the course of the following de-' scription of the elements, combinations, arrangem'ents of parts, and applications of principles constituting the invention; and the scope of protection contemplated will appear from the claims.

,In the accompanying drawings, which show, by way of illustration merely, and as one example of how the invention may be carried out, an embodiment thereof adapted to be attached to a sash-sticker,

Fig. 1 is a top plan view, partially broken away and partially in section,the stile not yet being advanced toward the rotary cutter;

Fig. 2 is a view similar to Fig. 1,'but showing certain of the parts redisposed and the stile partially horned;

Fig. 3 is a view similar to Figs. 1 and 2, but showing certain of the parts further redisposed and the horning operation prac-. tically completed;

Fig. 4 is a vertical section, taken on line Like characters of reference referto like parts throughout the several views of the drawings i 1 i 'The'main support or bed is shown at. 8; which support or bed may desirablynform "a part of a familiarsticker, shaper, spind-le machine or thelike, so aspreferablyv to employ the newlapparatus as anatt'acliment-for a sash-sticker or similar maohineend in such position that the 'cuttin'g device etthe new apparatusmayhorneach window stile as itgoes through the sticker. Y Despite the'apparent firstglance. complexity of the drawings, thenew apparatus, as here illustratively embodied, comprises but very few parts.- a V i These-parts include an upright milling fixed on a vertical shaft 10 andcutter '9, 1 adapted to be rotated'by any suitablepower means (not shown to constitute a cutting device for horning the endof a stile 10 advancedtoward the cutter; a cuttersguarid 11 loosely taking 'the shaft 9 above and below the cutter as indicated best at 11 1-111 Fig. 1, and a-pair of upperand lowerfhorr zontal'plates 12 and 13. Thelower plate 13 fixed to bed 8 in any suitable manner. The upper plate 12, carrying rigidly a stileholder or carriage 14 (so that really this plate 12 and the carriage are one structure constituting the complete carriagel is edgewisel'y movable relative to the lower plate 13, by means of post and slotconnections hereinafterdescribed more in detail,-first, to have a nievement of translation alonga straight line, to perform the first part of the stile-horning cut, and, finally, to have a movement of i-otatio11about a fixed point, to perform the second part of the stilehorning cut. Y J

The only other elements of the apparatus arercoact ng slots and posts, as just mentioned certain of which are carried b late 12, and certain of which are carried by plate 13, for guidingtheupper 'plate 12 to have a translat onal movement and an ensuing rotational movement in its own plane while sliding over lower plate 13; a pedal .15 (Fig.- l for giving the said upper plate its movement of translation, to advance the stile end toward the cutter; ar-etractile coil-spring 16 (Fig. &) normally urging the sliding plate 12 to hold thestile'end away from sail cutter; a handle 17 (Fig. 1) forming arigid prolongation of carriage lt fixed on top of upper sliding plate 12, for giving said upper plate its movement ofrotation; and an operative connection between cutterguard 11 and said upper plate, such conduced extension horning of the stile progresses.

"plate.

arm 18 fixedly offset from the bottom. of

the guard and having its slot engaged by the lower portion otthe'shank of a depending threaded rod 19 the upper end of which is clamped by nuts as illustrated to a re- 12? of upper sliding plate 12, thereby automatically and continuously to vary the setting r the cutter-guard for maximum. protective action. at all itimesas Referring now particularly to the coacting slots and posts certain otwhich are can riedas aforesaid by each: of the plates '12, and 13, compare Figs-,fiand 7 with Fig. 1. The lower fixed plate 13 of Fig. 7 has, cut tberethroug'h a pear-shaped slot 20 and an- L-shaped slot 21; and upper sliding plate 12 has cut therethrough.- a straight slot 22 and an L-shaped slot 23. E achcot the two slots in each of the plates takes its own separate post fixedly carried by the other to Jig. l, posts 20" and 21*, respectively taking the slots 20., and 21 in the lower plate 13, are securely mounted to, depend from the upper plate 12; while, referring for a moment alsoto Fig. 5, I spectively taking the slots 22 and 23in theupper plate 12, lower plate 13 to extend above the same.

The stile-holding carriage 1 lbeing=screwed fixedly atopjthe .upper sliding-plate 12, as by means of the three screws marked 24c in Fig. 3, all the slots and posts except slot 21 and post 21? are hiddenin Figszl, 2 and 3. Referring .next to the function of the spring 16 of Fig. 4:, which spring, it willbe noted,'is stretched between a hook 24 at the lower end of threaded r d 19am. a hook 25 carried atthe lower end of aswiveled stud 26 set in. a suitabl drilled hole in the bed are securely mounted on.

Thus, referring for a moment also osts 22a and 23 re- 8 of the main machine, it will be seen from,

a reference to Fig. 1, that such spring normally urges the parts to maintainthe-relative positions there shown and impositively locks said parts in these positions by applying pressures away from thecutter tothe pins 20and 21 carried by the upper sliding plate; and itwill further be seen by a refer{ ence toFigs. 2 and 8, that the same spring, t pa re move from he V as soon as positions of Fig. 1 .to thoseof Fig. 2, 11111116 diately urges the partstoward the posit 'O-m of Fig. 3, thatis, applies pressures away from, and to the left of the cutter, to the same pins 20 and 21 carried by the upper sliding plate. 7 1 v Referring next to the'operative connection-between pedal 15, which pedal is. pivotally mounted as indicated at 27 in Fig, 4, it

will be seen that the rear end oithe pedal connected by link 28 to .a. lever 29 piveted at. 30, the upper end of which lever is co n nected by a cable 31 to a hook 32 at the lower end of a rod 33 forming a prolongation of post 21. Y

The just-mentioned pivotal mounting for lever 29 is afforded by adepending bracket 34 carried by a member or housing 35 forming a part of the new apparatus and suitably attached to bed 8 of the sash-sticker. This structure 35 carries suitable journalling supports (not shown) for shaft 9 of cutter 9.

With the parts arranged as shown in Fig. 1, and with the cutter 9 of course rotating in a clockwise direction, a stile 10, having been slid all the way into carriage 14c, is advanced at the angleindicated toward cutter 9, as the result of a straight-line movement upper sliding plate 12 toward the cutter; this movement of the upper sliding plate following from a depression of pedal 15 against the tension of spring 16, and a consequent travel of pins 20 and 21 in their slots toward 'the'cutter and a simultaneous travel of slots 22 and 23 of upper sliding plate 12 past their posts. At the conclusion of such travel of upper sliding plate 12, the cutter '9 has completed the concave horning cut marked 36 in Fig; 2 and the posts and slots are disposed as shown in Fig. 2. Immediately upon this happening, pressure on the pedal 15 is released, whereupon spring 16 exerts a pull upon upper sliding plate 1.2 to give the same a tendency to swing aboutpost 22 fixed on lower fixed plate 13, as a result of which, and during the performing of the convex horning cut 37 of Fig. 3, the upper sliding plate 12 is rotated to the position shown in said Fig. 3. During such rotation the curved limb of slot 23- in upper sliding plate 12 travels past fixed post 23, and simultaneously posts 20* and 21 of the upper sliding plate travel through slots 20 and 21 of the fixed plate 13. These slots and posts are thus arranged as shown in Fig. 3 when the horning of the stile end is practically completed. In this connection it will be seen that the curved limbs of slots 21 and 23 and the long curved side of slot 20 are all arcuate on radii of different lengths but with each radius terminating at the center of post 22 when the parts are moved from the positions of Fig. 1 to those of Fig. 2. As soon as the stile end is completely horned as just described, the attendant grasps the handle 17 and pushes the same to redispose the parts from the positions of Fig. 3 to those of Fig. 2; whereupon spring 16 again automatically functions, this time to throw the parts back to the positions of Fig. 1. During the operations above de scribed in order, it will be seen that the pin and slot connection afforded by the parts 18 and 19 between sliding plate 12 and cutter guard 11 automatically functions to shift the guard relative to the cutter as required from the scope thereof, it is intended that all 'matter contained in the above description or shown in the accompanying draw ngs shall-be interpreted as illustrative and not in a limiting sense.

It will also be understood that the language used in the following claims is in tended to cover all the generic and specific features of the invention'herein described and all statements of the invention which, as a matter of language, might be said to fall therebetween.
